Last week Italian site ComingSoon.it announced that the European tour this year has been cancelled. (Google translated) "With deep regret that we receive the news of the cancellation of all the European tour by KISS , then also the date on June 3rd on the stage of the GODS OF METAL 2016."

The article was pulled, and then re-appeared with no official announcement being made. Since then the German dates have also been cancelled and the dates have all been pulled from KISS Online. However, there has still been no official announcement so nobody outside of the band knows what is going on regardless of some of the rumours that have spread elsewhere, it's possible that things have just been rescheduled to allow for a full US tour.
